Therefore, when the cylinder moves downwards, the dust hood is firstly contacted with an object to be carved and milled or the mounting seat, the cylinder moves downwards continuously, the dust hood moves upwards relative to the shell through the second sliding block, and therefore the cutter set moves downwards to conduct carving and milling.

Preferably, the second sliding groove is a dovetail groove.

Like this, can make the second slider stable slide in the second spout, prevent that the second slider from jumping out the second spout.

Preferably, the third connecting block is composed of a channel, an annular outer edge, a disc-shaped inner plate and a connecting rod for connecting the outer edge and the inner plate, the connecting rod is fixedly connected with the inner plate, and the drilling sleeve is fixedly connected with the outer edge.

In this way, debris or dust can be caused to enter the suction device through the passageway.

Preferably, the cross section of the bottom of the connecting rod is arc-shaped or inverted triangle.

Therefore, the situation that the residual dust or the dust is blocked by the connecting rod and cannot be sucked by the dust suction equipment can be avoided.

Preferably, the connecting rod is provided with a thread drill tooth.

Therefore, the residual scraps are smashed through the thread matching milling cutter, and the residual scraps are quickly taken out through the thread drilling teeth.

Preferably, the milling cutter is in a slope shape inclined inwards.

Thus, the slope is inclined inwards to guide the scraps inwards, so that the scraps generated by drilling can be concentrated inwards and then are taken out by the channel or the thread rotating teeth.

Preferably, the lower eaves of the milling cutter is higher than the bottom of the drill bit.

Thus, when the milling cutter rotates for engraving and milling, the inner ring of the milling cutter is drilled by the drill, and the deformation reduces the strength required by the operation of the milling cutter.

Compared with the prior art, the carving and milling machine adopting the technical scheme has the following technical effects:

during the use, start first motor, drive the slide and begin to move on first ball, start the cylinder, the cylinder drives fourth connecting block downstream, thereby drive carving and milling machine main shaft downstream, it is rotatory that carving mills the quick-witted main shaft and drives cutter group, process the article, start the second motor, it moves on second ball, thereby drive carving and milling machine mount pad and begin to move to one side, add man-hour, dust collecting equipment absorbs the collection through hose and suction hood to the dust that produces in the course of working, simultaneously, the drill bit rotates article and can be milled garrulously by milling cutter and through the space screw thread commentaries on classics tooth guide discharge promptly, be inhaled away by dust collecting equipment through the hose.
